Answer:
because melted wax is still wax and flammability is just a chemical property
Explanation:
Answer:
its atmosphere is made up of mostly carbon dioxide
Explanation:
Answer:
Ketones and ketoacids are alternative fuels for the body that are made when glucose is in short supply. They are made in the liver from the breakdown of fats. Ketones are formed when there is not enough sugar or glucose to supply the body's fuel needs. This occurs overnight, and during dieting or fasting.
Explanation:
Answer:
Explanation:
The given chemical formula is;
4H₂O H₈O₄
H₂O signifies 2 atoms of hydrogen bonding with 1 atom of oxygen
H₈O₄ signifies 8 atoms of hydrogen bonding with 4 atoms of oxygen
The 4 coefficient before H₂O signifies the number of moles.
It appears H₂O is 4 moles of water
H₈O₄ is 1 mole of the compound
The number of moles of each of the compound differs.
The density of a sample of nitrogen gas (N₂) that exerts a pressure of 5.30 atm in a 3.50-L container at 125°C is 4.54 gm/litre
<h3>What is the
Ideal Gas Law ?</h3>
This law combines the relationships between p, V, T and mass, and gives a number to the constant.
The ideal gas law is:
pV = nRT
where n is the number of moles, and R is universal gas constant.
The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K
The values given in the question are
p= 5.30 atm , V=3.50 L
T (in Kelvin) = 125+273 K
= 398 K
R = 0.0821 L·atm /mol·K
The Ideal Gas equation can be re written as
pM=DRT
M is the molar mass , D is the density
M for N₂ is 28 gm/mol
so density can be determined as
Therefore the density of a sample of nitrogen gas (N₂) that exerts a pressure of 5.30 atm in a 3.50-L container at 125°C is 4.54 gm/litre
